The BPR-1a Basic Power Relay is designed to allow seamless integration of controllers, devices and equipment in gardens, greenhouses, grow rooms or other environments. The BPR-1a can operate in a Normally Off mode – where the trigger cable activates attached devices – allowing controllers or timers to operate multiple pieces of equipment or larger amounts of amperage. The BPR-1a can also operate in a Normally On mode – where the trigger cable turns off attached devices – allowing controllers or timers to coordinate various functions (for example, turning CO2 equipment off when ventilation fans activate).
